JOURNAL-BOX vAND LUBRICATOR FOR CAR-AXLE JOURNALS.

Specication of Letters Patent.

Application led January 27, 1917` Serial No. 144.920. Renewed February 10` 1919. Serial No. 276,179.

To all 'whom t may concern:

Be it known that I, LAoEY Y. WILLIAMS, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Journal-Boxes and Lubricators for Car-AXle Journals, of which the following is a specification.

The object of the invention is the provision of a combined journal box and lubricator, said journal box, interchangeable with the well known type of M. C. B. journal box, having oil receptacles formed` therein the walls of which are integral with the box and from which receptacles oilmay be delivered by gravity and capillary attraction to the exposed surface of the journal below the bearing, thus insuring constant ,lu

' brication under all conditions of service.

method of procedure I have so fardevised for the purpose.

To admit of its interchange with the M.

C. B. type of box the general dimensions as to size and exterior shape must conform` to the adopted standard so it may receive the pedestal jaws or securing bolts of the truck frame, consequently the receptacles must be formed inside the box and means be provided for `filling the oil receptacles and removing land inserting the detachable parts throughy the box end opening normally closed by the movable cover or lid.

. Figure l is a vertical section in elevation of my improved box lubricator, the ournal being in position.

Fig. 2 is a cross section/ofthe complete box on the line 2-2 of Fig. 1.L

Fig.y 3 is a horizontal sectional plan view of the entire box. l n .l

Fig. 4 is a perspective View of one oil dis-v parts separated to tension of the receptacle under'the lug which is engaged by the bearing above the journal.

- When formed by casting, the box is preferably integral and has vertical walls A Aat each side inside the box and spaced some distance from the vertical exterior sides 1, 1 of the box.l `B and C are the end walls which form with the walls A A and the sides of the box two oil receptacles each substantially of the same length? as the journal 2. These receptacles are closed at the top by the metal of the top of the box and the only openings are those at the bottoms, as D D, for the feeding of the oil to the y'distributers E E, and at the ends, as F F, for introducing oil into the receptacles.

The oil distributers E E are each preferably of fabric Gr composed of textile material and spring brass wire, or alternate layers of cotton and woven spring wire, having at one edge a carrier II consisting of a U- shaped strip of metal between the edges of which one edge of the fabric G is securely fastened.

The lower edge or flange I of the carrier is wider than the upper edge and adapted to frictionally engage a longitudinal ledge or seat J on the inner vertical surface of the side of the box and locatedbelow the opening or openings at the bottom of the oil receptacle.

To hold the carrier in place a fiange K is provided which is seated within a recess L formed at the back of the ledge or seat J. The top surface ofthe carrier engages the lower edge `ofthe end walls bounding the reccptacle so it is securelyheld in position. Obviously, each distributer can be slid endwse into position upon the ledge and also withdrawn by opening the end cover or lid 3 of the box, and after their insertion oil can be introduced to the receptaclesby way of the openings F F near the tops of the front end walls vbounding the receptacles.

It will be observed that the fabrictextile materialand thespring wire-bears against the lower edge of a wall A and closes the opening oir-,openings at the bottom of the receptacle, and that the oil is fed to the side surfaces of the journal by gravity and capinllary attraction. The spring textile fabric maintains its position automatically in frictional contact with the journal and the flange I of the carrier aids in holding the same in position.

In removing the journal from the box and inserting the same the collar 4: on the journal can temporarily bend the fabric sidewise without injuring it in any way.

Attention in particular is called to the shape of each oil receptacle. In common practice a bearing 5 and a key or wedge 6 are located between the journal and the top inner surface of the box, the bearing fitting back of the collar el and having a iange 7 back of the rear end of the wedge, which latter at its front end is confined against movement outwardly by lugs 8. To prevent rearward movement of the bearing the inner surface of the box has inwardly projecting lugs 9, 9 which are engaged by lugs upon the bearing at each side, all of which will be readily understood by those skilled in the art. These lugs 9 cannot be omitted, and consequently the spaces forming the oil receptacles, see Fig. 4:, extend at each side and below the lugs.

In removing and replacing a bearing 5 obviously the distributers need not be removed.

Other parts of the box than those mentioned need not be described, as they are of the well known shapes and locations and dimensions shown by the M. C. B. type of box. I-Iowever, changes in the box may be introduced which will allow unsubstantial changes in the lubricating elements without renderin(T the box non-interchangeable with the M. B. types of boxes.

In operation the oil feeds by gravity and capillary attraction to the journal, and the flow of oil is determined by the amount which replaces the oil distributed from the fabric to the surface of the journal, for there is no dripping of oil from the fabric to the bottom of the box.

What I claim is: Y

l. A combined journal box and lubricator having oil receptacles formed inside the box and at the opposite inner sides thereof, each of said receptacles being provided with an opening at the bottom, and a removable oil distributer for each receptacle located and supported so as to engage the metal bounding the opening and close the same and adapted to bear against a journal; said oil distributer being slidable longitudinally of the journal into and out of position.

2. A combined journal box and lubricator having oil receptacles formed inside the box and at the opposite linner sides thereof, each of said receptacles being provided with an opening at the bottom, and a removable'oil distributer for each receptacle slidable 1ongitudinally of the journal into and out of position; each oil receptacle space extending each side of and below the wedge stop lug 9, in substance as set forth.

3. A journal box having oil receptacles inside the box at its opposite inner vertical sides with openings at the bottoms of said receptacles, and a ledge or seat below each receptacle to support an oil distributer which is slidable longitudinally of the journal into and out of position'on said ledge or seat.

4. A journal box having oil receptacles formed inside the box, one at the inner surface of each vertical side, the walls bounding the receptacles being cast integral with the box; each of said receptacles having an opening at the bottom, and means -below said opening to support a removable oil distributer which is slidable longitudinally of the journal into and out of position when the box lid is open.

5. A journal box having oil receptacles formed inside the box, one at the inner surface of each vertical side, and oil distributers one for each receptacle slidable longitudinally of the journal into and out of position through the end opening of the box; the openings in the walls of the receptacles for introducing oil being inside the box.

6. A journal box having oil receptacles inside the box and at the sides, a ledge or seat for a distributer adjacent the bottom of each receptacle, and a distributer slidable longitudinally of the journal into and out of position on the ledge or seat.

7. A combined journal box and lubricator, the box having oil receptacles formed inside the box one at each vertical side with an opening at the bottom, and removable distributers one for each 'receptacle and each distributer provided with a fabric of textile and spring wire, said distributers being` slidable longitudinally of the journal into and out of position through the box end opening.

8. A journal box having oil receptacles formed inside the box and each receptacle provided with an opening at the bottom, a distributer for each receptacle comprised of textile spring fabric and a carrier, and means for removably supporting the distributer against the metal bounding the opening of a receptacle so the entire flow of oil will be received by the textile and spring fabric and transferred by capillary attraction to a journal; each distributer being slidable longitudinally of the journal into and out of position.

9. The combination of a journal box having oil receptacles at the vertical sides inside the box and each provided with an opening below Vthe bearing surface of the journal, and oil distributers removably supported adjacent the said openings and slidable longitudinally of the journal into and out of position, each distributer being provided With a yielding spring fabric adapted to engage the bearing surface of the journal, whereby the fabric may automatically adjust itself in position.

10. Avcombined journal box and lubricator, the outer surfaces of the side Walls of the box lying in substantially vertical parallel planes, oil receptacles located at the sides of the box entirely inside the outer side Walls thereof, the inner Walls A A of said receptacles being disposed adjacent to the journal and bearing, and oil distributing means inside the box insertible and removable only at the open end of the box.

l1. A combined journal box and lubricator, the outer surfaces of the side Walls of the box being disposed in substantially vertical parallel planes, oil receptacles located at the sides of the box entirely inside the outer side Walls thereof, and yieldable oil distributing means located inside the box and insertible and removable only at the open end of the box.

12. A journal box having oil receptacles at the sides inside the box, and distributing means for oil in connection with the receptacles, said distributing means being insertible and removable only at the open end of the box.

In testimony whereof I aiiix my signature.
